There are lots and lots of evidence of Gods existence.
1. The universe had most probably a beginning.
This is supported through scientific, and philosophical reasons. Therefore it had a cause. Since beyond our universe, there was no time, no space, and no matter, that cause must be timeless, beginningless, eternal, spaceless, transcendent, invisible, personal, and incredibly powerful. Why does it need to have these characteristics ? This cause cannot exist in the time/space/material universe because then it would exist within the very universe it created. That is impossible.
Whatever caused the universe, existed beyond the universe. Since the universe had a beginning in time, and since matter and energy do not spontaneously change and arrange themselves into something new, then the best explanation for the cause of the universe is an action that was a decision.The cause must be personal because an impersonal force would be deterministic and mechanistic, not possessing free will. A mechanistic being only operates according to the programming it received from something else. But if the cause of the universe received programming from something else, then we have again not provided the answer to the cause of the universe. We have just found a middle-man. The cause had to make a choice to create and only beings who are personal can make choices.That description fits best to the God of the bible.
2. The universe is finely tuned to permit life on our planet.
Over 120 fine tune constants are know up to know, and as more time pasts, more are discovered. This might be due to chance, to physical need, or to design. Chance is a very bad explanation. Some advocate a Multiverse. But to have just one life permitting universe, you need 1 to 10^500 attempts to get it done. Thats a 1 with 500 zeros. If we put it in comparison, that in our universe, there exist around 10^80 atoms, this shows how improbable it is, that a Multiverse could explain finetuning. Beside this, the Multiverse argument does not explain away God. A mechanism needs to be in place to trigger these multiverses. It could not be by physical need, since if so, why are there many planets, which are not life permitting, but our is ? So its best explained by design. Our earth/solar/moon system is a very strong evidence. Our solar system is embedded at the right position in our galaxy, neither too close, nor too far from the center of the galaxy. Its also the only location, which alouds us to explore the universe, In a other location, and we would not see more than stellar clouds. The earth has the right distance from the sun, and so has the moon from the earth. The size of the moon, and the earth, is the right one. Our planet has the needed minerals, and water. It has the right atmosphere, and a ozon protecting mantle. Jupiter attracts all asteroids , avoiding these to fall to the earth, and make life impossible. The earths magnetic field protects us from the deadly rays of the sun. The velocity of rotation of the earth is just right. And so is the axial tilt of the earth. Beside this, volcano activities, earth quakes, the size of the crust of the earth, and more over 70 different paramenters must be just right. To believe, all these are just right by chance, needs a big leap of faith. This is indeed maibe the strongest argument for theism.
3. Life. Abiogenesis has not been able to explain the existence of life on earth.
Science cannot explain it. There are strong reasons to believe, a natural origin is not probable, and a bad explanation. First of all, why whould dead rocks need to evolve, to create life ? Secondly, just one living cell is more complex than the most complex machine created by man. A living eukaryotic cell contains many hundreds of thousands of different complex parts, including various motor proteins. These parts must be assembled correctly to produce a living cell, the most complex ‘machine’ in the universe—far more complex than a Cray supercomputer.DNA molecules carry information . Information is always created by a mind. There i no natural mechanism known to man, to create information. Information is by essence spiritual, and not physical. There is no bridge to cross the gulf from material to spiritual. Even through millions of years of evolution. Its not possible.
On the one side, we find the real world of objects, events, and tensional spacetime relations. On the other side, we find fully abstract representations that contain information about the material world. That articulate information is abstracted first by our senses, secondarily by our bodily actions, and tertiarily by our ability to use one or more particular languages . Between the two realms we find what appears to be an uncrossable gulf.
A small part of the evolutionists' problem is that hard objects are never observed spontaneously to transform themselves (on their own recognizance) into abstract ideas.
4. The moral argument, and value of life.
Life has no value. Everthing is permissible. There is no such thing as right and wrong because there is no all knowing and all powerful Creator to define what is good and what is bad. It becomes society who tries to define it. What does that matter though if the people making laws define right from wrong. They are just as human as any other person in the world. The only thing that truly exists is personal preference. What Hitler, Stalin, or any other mass murderer did was not wrong at all. They simply had a different personal preference than you do. The point is, you shouldn't tell anyone that they are wrong or even right because they aren't either of those things. You can believe that its wrong, but you have no place to ground it. People can do anything they want to do without getting punished for their actions if the world lived consistently with the belief that God doesn't exist. How do you explain where guilt comes from? How do you explain why all people in the world have this feeling called a conscience that seems to tell them that something is wrong, such as murder. How come people feel a heavy weight on their emotions called guilt when they do something wrong, such as lie and steal, and the best thing to do to take the weight off themselves is to tell the truth and/or ask for forgiveness. If God doesn't exist, then how could you rationally explain all that?
5. Without God, life has no reason to be, there is no ultimate goal
There is no purpose to life. Life has no ultimate goal. There is no reason for living. Sacrifice for someone else's life would be stupid. This argument shows that an atheist lives inconsistently with their own belief. If a murderer who believed murder to be ok, came into your house to brutally murder you and your family, would you think that HE is wrong to do that? If you said no, that he isn't doing any thing wrong, then you would be living consistantly with your beliefs. But if you said yes, then you would live as if there were objective morals. But if there is no god to define objective morality then there is only subjective morality. So by saying it is wrong makes it only your opinion, but not the murderers opinion. You would be "pushing your<br style="position: static !important; ">morality on him" which is the opposite of what you believe. You probably believe that "it is wrong to push your morality on another person." Even that statement right there is another objective moral statement. In other words you express your opinions, but don't always live by them.
6. Religious experiences and miracles
What ever culture you go into, people are incurably religious. In every culture you see three things. 1) Everyone, except the atheist, worships a being higher than themselves. 2) Everyone has a morality they cannot keep. 3) Everyone is psychologically unsatisfied. People feel an emptiness in themselves that they want to fill. If the material world was the only thing that existed and if all your material needs were met, you should be satesfied right? But how come people who have the most wealth are usually the most unhappy. They constantly want more and more. And how can you explain the millions of people in the world who say they have felt the closeness of God in their lives? I personally am included with them. I have felt God's presence in my life on a consistent basis. Now how can you rationally explain that without God's existence? There are many people in the world who report seeing miracles. In other words there are people who say that they saw a situation occur where there is no naturalistic explanation for it. I personally know people who have had miraculous situations occur, such as immediate healings. You might argue that science will someday explain those things, but right now you can't explain them. The best explaination is God, because if God created the world then it wouldn't be hard to believe that he can intervene supernaturally in this world.
